missing files

[neil84]

Hi all,

I don't know what happened but actually display refreching is about 3 seconds.

I remarked that when I open a VI tha uses tne display VIs, Labview is searching on  "update.ctl" and other files. these files are not in "C:\Program Files (x86)\National Instruments\LabVIEW 2009\vi.lib\Embedded\ARM\EK-LM3S8962\display"

I allready tried to reinstalle Labview and ARM module, but the files are not reinstalled.

How to solve this?

thanks

This happen only if you try to use VIs from a previous version (8.6).
When open the VI press "Ignore Item" button, and then just replace all instances of update.ctl with booleans, perhaps only TRUE or FALSE constants:

I have no 8.6 version istalled.

I did that but the refreshing is always too late.

The refresh rate might be affected by your algorithm: number of display VIs, string convertion, etc.

I just can asure you the update (which sends the entire display memory to OLED) takes about 60 – 100 ms in a faire system (the task making the update is allowed to run)

The refreshing is too late even with the Analog input example from "Find Examples"

I just modified the AI.vi from the mentioned example so I can estimate the "refresh rate" (see only if next ms is indeed the next one)

These are results for 100ms (left) and 30 ms (right):

So the code can't be the responsible.

You said that it's not the missing ctl too.

What can it be so?

You're trying to become an engineer.

Show us some quntitative results.
